Fireproof coated structure for penetration part
Provided is a fireproof coated structure for providing fireproof coating to a penetration part (11) formed in a fireproof beam (20) of a wooden building, wherein a cylindrical fireproof coating material (12) covers the inner peripheral surface of the penetration part (11) so as to be attached to the penetration part (11). The cylindrical fireproof coating material (12) is formed when a plurality of gypsum board pieces (13a), which are cut off from a commercially available gypsum board (13) that has a thickness of 9.5-25.5 mm, are integrally joined to each other in a state of being laminated in the thickness direction. The cylindrical fireproof coating material (12) is inserted into the penetration part (11) so as to be attached thereto in a state where joint parts (15) of the gypsum board pieces (13a) adjacent to each other in the lamination direction are disposed at boundary parts (23) between a coating member (22) and structural members (21) of the fireproof beam (20) or at portions near the boundary parts (23).
